Offering high quality, versatility, and longevity, TIG is the most commonly used stainless steel welding process. This welding process creates a low heat input, which makes it perfect for thin material. The argon gas is often mixed with other gases, depending on the needs of the specific project, including helium, hydrogen, and nitrogen. To prevent oxidation and increase resistance to corrosion, a single-sided welding process can be used creating inert backing gas protection between the interior and exterior welds.
